The present invention claims priority of Korean Patent Application No.10-2008-0130142, filed on Dec. 19, 2008, which is incorporated herein byreference.

FIELD OF THE INVENTION

The present invention relates to a method for remotely maintaining andrepairing various devices in a ship; and, more particularly, to anapparatus and a method for integrally managing a number of and differentkinds of local devices in a ship in a standard form through ahierarchical ship device management architecture (SDMA) for providingautomatic configuration management, maintenance management, and serviceinstruction management of the local devices; and an inter-workingframework (IWF) structure for exchanging and integrating data andgenerating new data by connecting an operation mechanism to the localdevices of a sub-system independently operated in a ship.

BACKGROUND OF THE INVENTION

In current ship environments, a number of ship devices build and managevarious legacy environments based on their own protocols. Therefore, inthe current ship environments, there is no structure for integrallymanaging local devices of independent sub-systems of a ship due todifferent properties between device management and information ofindependent systems of the ship and information of the various localdevices of the ship is not shared by the sub-systems, providing onlytheir own device management and approach method through independentlocal protocols.

FIG. 1 is a block diagram illustrating an existing complex navigationdevice for a ship. As illustrated in FIG. 1, a navigation automationsystem and an engine monitoring/controlling system constitute a complexnavigation device for a ship integrated by a database and a network. Thecomplex navigation device includes an own ship database (OSDB) systemincluding a local area network (LAN) constituting a dual network, a mainserver for an OSDB connected to the dual LAN, a common storage, and anOSDB backup server, an engine system connected to the dual LAN tocontrol and monitor a main engine remotely and in real time, and aplurality of client systems. In that regard, each system is constitutedby a main network connected by an ATM switch of the LAN and a backupnetwork connected to a switching hub. The structure enables a land headoffice or a management department to control and monitor management ofthe ship.

In order to build a complex navigation device for a ship, the existingtechnology collects information from sub-systems in the ship such as adatabase 100, a navigation automation system 102, an unloadingmonitoring system 110, an engine monitoring system 108, a introversionperformance evaluation system 106, and an ISMS 104 by connecting thesub-systems using a dual LAN 120; stores the collected information inthe database 100; and manages the ship device based on data stored inthe database 100. However, different properties of local device managingmethods and information of the independent systems of the ship makesintegration and management of local devices of the independentsub-systems difficult.

Since the existing technology cannot integrally manage the differentsub-systems for the ship and cannot suggest a structure and a protocolfor interoperating different ship devices, there is a limit in a shipdevice managing method capable of accommodating various device groupsand legacy protocols in a ubiquitous ship environment.

FIGS. 6 and 7 illustrate operation control flows in which differentlocal devices in a ship are automatically and dynamically configuredthrough LD, LDM, and DM middleware components in accordance with anembodiment of the invention.

Referring to FIG. 6, when a new LD 206 is to be connected to a shipdevice management structure network including the DM 200 and the LDM204, it receives an advertisement message from the LDM 204 and thentransmits a search request message.

Then, the LDM 204 transmits a search response message as a response tothe search request message, and the LD 206 discovers an address of theLDM 204 and sets up a session for network connection to the LDM 204 tobe connected to the network. Accordingly, the LDM 204 creates a tablefor the newly connected LD 206 and allots the LD 206 with an ID toregister the LD 206.

Referring to FIG. 7, when the new LDM 204 is to be connected to the shipdevice management structure network including the DM 200 and the LDM204, it receives an advertisement message from the DM 200 and thentransmits a search request message.

Then, the DM 200 transmits a search response message as a response tothe search request message, and the LDM 204 discovers an address of theDM 200 and sets up a session for connection to the DM 200 to beconnected to the network. Accordingly, the DM 200 creates a table forthe newly connected LDM 204 and allots the LDM 204 with an ID toregister the LDM 204.

FIG. 8 illustrates an operation control flow for collecting informationof a newly connected LD in accordance with an embodiment of theinvention.

Referring to FIG. 8, the LDM 204 transmits a queryDeivceList requestmessage to obtain all lists of the newly connected LD 206, and the LD206 transmits the lists of local devices to the LDM 204 through thequeryDeviceList response message.

Then, the LDM 204 transmits a queryDeviceInformation request message tocollect information for each device managed by the LD 206.

Thereafter, the LD 206 transmits information regarding the devicemanaged by the LD 206 to the LDM 204 through the queryDeviceInformationresponse message, and the LDM 204 that has received thequeryDeviceInformation response message updates correspondinginformation in a device database.

FIG. 9 illustrates an operation control flow in which the DM 200collects information of a local device managed by the LDM 204 accordingto the embodiment of the invention.

Referring to FIG. 9, the DM 200 transmits a queryDeviceList requestmessage to obtain all device lists managed by the LDM 204, and the LDM204 transmits local device lists to the DM 200 through a queryDeviceListresponse message.

Then, the DM 200 transmits a queryDeviceInformation request message tocollect information regarding a local device managed by the LDM 204, andthe LDM 204 transmits information regarding the corresponding localdevice through a queryDeviceInformation response message. Thereafter,the DM 200 updates a database regarding the local device.

FIG. 10 illustrates an operation control flow for releasing connectionof the LD in accordance with an embodiment of the invention.

Referring to FIG. 10, the LDM 204 periodically transmits a queryAliverequest message as a heartbeat message to check whether the LD 206registered in the LDM 204 itself is alive. Then, when there is noresponse message for a specific period of time, the LDM 204 determinesthat the connection to the LD 206 is released and informs the DM 200that the connection to the LD 206 is released after deleting informationregarding the LD 206 from the database.

Accordingly, the DM 200 perceives that the connection to the specific LD206 is released through a message query/response regarding the devicestate with the LDM 204, and then deletes information regarding the LD206 from the database.

FIG. 11 illustrates an operation control flow for releasing connectionto the LDM in accordance with an embodiment of the invention.

Referring to FIG. 11, the DM 200 periodically transmits a queryAlivemessage as a heartbeat message to check whether the LDM 204 is alive.Then, when there is no response message for a specific period of time,the DM determines that connection to the LDM 204 is released and informsa maintenance service center (MSC) and a remote server (RMS) located ata remote place connected through a wired/wireless communication networkof information regarding the LD whose connection is released afterdeleting information regarding all LDs managed by the LDM 204 from thedatabase.

FIG. 12 is an operation control flow in which the RMS and MSC 600performs a monitoring and controlling operation of the LD 206 in theship device management structure network structure in accordance with anembodiment of the invention.

Referring to FIG. 12, the RMS and MSC 600 connected to the DM 200through a wired/wireless communication network and located at a remoteplace transmits a queryControlMonitoring request message to the DM 200to check the function state of the specific LD 206 in the ship.

Then, the DM 200 that has received the queryControlMonitoring requestmessage transmits the request message to the LDM 204, and then, the LDM204 that has received the queryControlMonitoring request messagetranslates a standardized meta protocol message into a local message ofa local protocol through the IWF 202 and transmits the translated localmessage to the LD 206.

Accordingly, after the LD 206 that has received thequeryControlMonitoring request message from the LDM 204 performs acorresponding functional operation, it transmits a response message ofthe controlling/monitoring result to the LDM 204 and then the LDM 204transmits to the DM 200 the response message of thecontrolling/monitoring result transmitted from the LD 206. Then, the DM200 transmits to the RMS and MSC 600 a response message of thecontrolling/monitoring result transmitted from the LD 206 and reportsthe controlling/monitoring result.

FIG. 13 illustrates an operation control flow in which the RMS and MSCmanages the state of the LD in the ship device management structurenetwork structure.

The DM 200 continuously maintains and manages recent state informationregarding the LD 206 to provide information regarding a lifecycle (INIT,ACTIVE, INACTIVE, and BLOCKED), a functional state (for example, LampON/OFF), and a performance state (for example, CPU occupancy, usage of amemory and HDD, usage of a network) of the LD 206 to the RMS and MSC600.

Hereinafter, an operation of managing a state of an LD will bedescribed. First, when there is a control instruction regarding the LD206 registered in the ship device management structure network from theRMS and MSC 600, the DM 200 updates a recent state of the LD 206 in adatabase through transmission/reception of a query/response message toand from the LDM 204 managing the LD 206. Further, when a device eventoccurs in the LD 206, the DM 200 updates in a database recent stateinformation of the device to maintain the recent state information.

FIG. 14 illustrates the concept of a lifecycle of the LD in accordancewith an embodiment of the invention.

Referring to FIG. 14, the INIT state of the LD 206 represents a state ofinitializing and invocating a necessary resource according to the deviceinitializing policy.
